Abstract/Summary Suffusion is one major reason for dysfunctions of earth dams and embankments. Suffusion as a self-filtration process occurs when loose grains are mobilised and transported through a series of pores interconnected by pore constrictions formed by the skeleton. For the assessment of suffusion, the grain size distribution is divided into two parts: (i) skeleton, which transfers the load and forms the basic soil skeleton; and (ii) loose grains, which can be mobilised and removed by seepage flow. To date, most suffusion assessment methods based on self-filtration criteria assume that there is a sharp boundary in grain size distribution between soil skeleton and loose grains fraction. This paper suggests a new self-filtration criterion for suffusion assessment which was developed on a numerical approach on the grain scale. The major difference to existing criteria is the introduction of a smooth boundary between the skeleton and loose grain fraction. The new method has been tested with data from some experimental studies
